松突圆蚧匀鞭蚜小蜂Encarsia sp.在1989年从日本引进到广东,在室内能用茶钹盾蚧Abgrallaspiscyanophylli来大量繁殖。在25～28℃恒温下,发育历期为23～26天,成蜂寿命1～3天,与温度关系密切。成蜂羽化高峰在羽化后的第2～4天,每日的羽化高峰在12时～20时.此蜂是产雌性孤雌生殖,在30.04℃下,能产卵和完成发育,但子代成蜂寿命仅数小时;当温度在32.01℃时,成蜂仍可产卵和幼虫早期能发育,在33.03℃时,幼虫则不能发育;在适温条件下,平均每天产卵4.3±5.8粒。
Encarsia sp. Was introduced from Japan to Guangdong in 1989 and can be multiply indoors indoors using the cymbidium Abgrallaspiscyanophylli. In 25 ~ 28 ℃ constant temperature, the development period of 23 to 26 days, into the bee life of 1 to 3 days, and temperature are closely related. The bee emergence peak in the first 2-4 days after eclosion, the daily emergence peak at 12 o’clock to 20 o’clock.This bee is female parthenogenesis, at 30.04 ℃, can spawn and complete development, but the offspring When the temperature is 32.01 ℃, adult bees can still lay eggs and larvae can develop early, at 33.03 ℃, the larvae can not develop; in the proper temperature conditions, the average daily egg laying 4.3 ± 5.8 grains .
